M22759/32-20-87 GRAY/VIOLET BTF STRIPE

M22759/32-20-87 Gray/Violet BTF Stripe – 20 AWG Silicone MIL-SPEC Wire for Fine-Gauge High-Temperature Harness Builds

The M22759/32-20-87 is a 20 AWG MIL-SPEC wire with a gray base and violet BTF stripe, silicone insulation, and a silver-plated copper conductor. Built to the M22759/32 military specification, it provides fine-gauge capacity with silicone-grade thermal performance for motorsport, aerospace, and high-performance vehicle wiring applications. Supplied pre-spooled.

Gray/Violet BTF Stripe: A Distinct Identification Combination

The gray base with violet BTF stripe (-87) offers a visually distinctive colour combination within the gray-base family. Violet is immediately differentiable from the other BTF stripe variants available on gray-base wire — including blue (-86) — making circuit identification straightforward in a finished multi-wire harness. The harness engineer assigns the specific circuit function; the consistent BTF stripe format ensures that assignment is traceable throughout the harness layout.

Silicone Insulation at 20 AWG

M22759/32 silicone wire at 20 AWG combines a fine conductor gauge with insulation rated at -65°C to +200°C continuous. This makes it appropriate for low-current signal and sensor circuits that must be routed through or near high-temperature components such as turbocharger housings, exhaust manifolds, or rotary engine housings where standard ETFE-insulated wire would operate closer to its rated temperature ceiling.
